Life (Basel) 2023; 13:1858. [PMID: 37763262 PMCID: PMC10532994 DOI: 10.3390/life13091858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 08/30/2023] [Accepted: 08/31/2023] [Indexed: 09/29/2023] Open
Abstract
Neural stem cells (NSCs) have previously been described up to the adult stage in the rat cochlear nucleus (CN). A decreasing neurogenic potential was observed with critical changes around hearing onset. A better understanding of molecular factors affecting NSCs and neurogenesis is of interest as they represent potential targets to treat the cause of neurologically based hearing disorders. The role of genes affecting NSC development and neurogenesis in CN over time on hearing capacity has remained unclear. This study investigated the mRNA abundance of genes influencing NSCs and neurogenesis in rats' CN over time. The CN of rats on postnatal days 6, 12, and 24 were examined. Real-time quantitative polymerase chain reaction arrays were used to compare mRNA levels of 84 genes relevant to NSCs and neurogenesis. Age- and hearing-specific patterns of changes in mRNA abundance of neurogenically relevant genes were detected in the rat CN. Additionally, crucial neurogenic factors with significant and relevant influence on neurogenesis were identified. The results of this work should contribute to a better understanding of the molecular mechanisms underlying the neurogenesis of the auditory pathway.

Potential Role of Protein Kinase FAM20C on the Brain in Raine Syndrome, an In Silico Analysis. Int J Mol Sci 2023; 24:ijms24108904. [PMID: 37240249 DOI: 10.3390/ijms24108904] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 05/04/2023] [Accepted: 05/05/2023] [Indexed: 05/28/2023] Open
Abstract
FAM20C (family with sequence similarity 20, member C) is a serine/threonine-specific protein kinase that is ubiquitously expressed and mainly associated with biomineralization and phosphatemia regulation. It is mostly known due to pathogenic variants causing its deficiency, which results in Raine syndrome (RNS), a sclerosing bone dysplasia with hypophosphatemia. The phenotype is recognized by the skeletal features, which are related to hypophosphorylation of different FAM20C bone-target proteins. However, FAM20C has many targets, including brain proteins and the cerebrospinal fluid phosphoproteome. Individuals with RNS can have developmental delay, intellectual disability, seizures, and structural brain defects, but little is known about FAM20C brain-target-protein dysregulation or about a potential pathogenesis associated with neurologic features. In order to identify the potential FAM20C actions on the brain, an in silico analysis was conducted. Structural and functional defects reported in RNS were described; FAM20C targets and interactors were identified, including their brain expression. Gene ontology of molecular processes, function, and components was completed for these targets, as well as for potential involved signaling pathways and diseases. The BioGRID and Human Protein Atlas databases, the Gorilla tool, and the PANTHER and DisGeNET databases were used. Results show that genes with high expression in the brain are involved in cholesterol and lipoprotein processes, plus axo-dendritic transport and the neuron part. These results could highlight some proteins involved in the neurologic pathogenesis of RNS.

NRG1/ErbB2 axis regulated mitochondrial function and antioxidant enzymes of neural stem cells in the cochlear nucleus partially through PGC-1α. Neurosci Lett 2023; 792:136942.

Abstract
Neuregulin-1 (NRG1)/erythroblastic leukaemia viral oncogene homologues 2 (ErbB2) pathway had been implicated in promoting differentiation and suppressing apoptosis of neuronal stem cells (NSCs) isolated from cochlear nucleus. In the current study, we aimed at determining the effects of NRG1/ErbB2 on mitochondrial (mt) function of NSCs. As expected, NRG1 increased the expression of mitofusin (Mfn) 1 and Mfn2 and decreased the expression of mitochondrial fission protein 1 (Fis1) and dynamin-related protein 1 (Drp1). However, after ErbB2 knockout, Mfn1 and Mfn2 expression decreased while Fis1 and Drp1 increased. Moreover, the increased mtDNA copy number and intracellular ATP level, elevated ATPase activities as well as decreased lactate production induced by NRG1 were partially reversed by ErbB2 knockout. Additionally, NRG1 treatment increased the activities of catalase, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and upregulated the protein expression of catalase, manganese superoxide dismutase (MnSOD), peroxisome proliferator-activated receptor-γ coactlvator-1α (PGC-1α), nuclear respiratory factor 1 (NRF1) and transcription factor A, mitochondrial (TFAM), which were also reversed by ErbB2 knockout. Furthermore, PGC-1α overexpression partially reversed the above effects of ErbB2 knockout. In conclusion, these findings suggest that the promotion of mitochondrial function of NRG1/ErbB2 axis is at least in part mediated by PGC-1α in NSCs from cochlear nucleus.

Abstract
Sensorineural hearing loss (SNHL) is a common causes of disability. Neural stem cells (NSCs) from the cochlear nuclei have been considered to be a potential direction for the treatment of SNHL. Neuregulin 1 (NRG1)/ErbB2 signaling displays an essential role in nervous system development. In this study, we aimed to explore the roles of NRG1/ErbB2 in differentiation and apoptosis of cochlear nuclei NSCs. The data showed that the expression of NGR1 and ErbB2 in cochlear nuclei NSCs isolated from rats were increased with the age of rats. NRG1 treatment reduced the nestin-positive cells number, increased the MAP2-positive and GFAP-positive cells number, decreased the expression of cleaved-caspase-3, and increased the activation of PI3K/AKT. ErbB2 knockdown by lentiviral-mediated ErbB2 shRNA infection reversed the effect of NRG1 on cochlear nuclei NSCs. LY294002 administration further enhanced the effect of ErbB2 silencing on the expression of nestin, MAP2, GFAP and cleaved-caspase-3. Taken together, NRG1/ErbB2 regulates differentiation and apoptosis of cochlear nucleus NSCs through PI3K/Akt pathway.

Low Molecular Weight Fraction of Commercial Human Serum Albumin Induces Morphologic and Transcriptional Changes of Bone Marrow-Derived Mesenchymal Stem Cells. Stem Cells Transl Med 2015; 4:945-55.

Abstract
Osteoarthritis (OA) is the most common chronic disease of the joint; however, the therapeutic options for severe OA are limited. The low molecular weight fraction of commercial 5% human serum albumin (LMWF5A) has been shown to have anti-inflammatory properties that are mediated, in part, by a diketopiperazine that is present in the albumin preparation and that was demonstrated to be safe and effective in reducing pain and improving function when administered intra-articularly in a phase III clinical trial. In the present study, bone marrow-derived mesenchymal stem cells (BMMSCs) exposed to LMWF5A exhibited an elongated phenotype with diffuse intracellular F-actin, pronounced migratory leading edges, and filopodia-like projections. In addition, LMWF5A promoted chondrogenic condensation in "micromass" culture, concurrent with the upregulation of collagen 2α1 mRNA. Furthermore, the transcription of the CXCR4-CXCL12 axis was significantly regulated in a manner conducive to migration and homing. Several transcription factors involved in stem cell differentiation were also found to bind oligonucleotide response element probes following exposure to LMWF5A. Finally, a rapid increase in PRAS40 phosphorylation was observed following treatment, potentially resulting in the activation mTORC1. Proteomic analysis of synovial fluid taken from a preliminary set of patients indicated that at 12 weeks following administration of LMWF5A, a microenvironment exists in the knee conducive to stem cell infiltration, self-renewal, and differentiation, in addition to indications of remodeling with a reduction in inflammation. Taken together, these findings imply that LMWF5A treatment may prime stem cells for both mobilization and chondrogenic differentiation, potentially explaining some of the beneficial effects achieved in clinical trials.
